I don't think that needs to be a terminal value. People's deliberate choices provide information about what will actually make them happy; with compulsions, we have evidence that those things won't really make them happy.

I agree that it's useful to have words to distinguish what we want long-term when we think about it, and what we want short-term when tempted, and I've just done a post on that subject. However, I don't see how that helps rescue the idea of blame and deserving.
